Title: Improvements in devices for practising golf
IPC: A63B69/00
Filed: 1926-07-30
Abstract: 276,812. Moon, J. July 30, 1926. Measuring the force of a blow.- A device for practising golf of the kind in which a captive ball, revolvable round a central axis, operates, through gearing, a dial pointer to indicate distance of travel of the ball is characterised in that the tethering medium is reversibly and detachably secured to the device, and to the ball by screw-threaded means which permit removal of the tethering medium at will from either, or both, the ball and the device. As shown in Fig. 1, the tethering medium in the form of a wire t is secured to a threaded bush w in the ball by means of a screw-threaded split pin v, and is secured by a similar split pin v<1> to a collar c revolubly mounted on a fixed spindle d. The ends of the wire tare looped and are attached to the split pins v, v<1> by passing the loops between the limbs of the pins. The spindle d is utilised to secure together the upper and lower casings a, b of the device. At each revolution of the collar c a projection g thereon rotates a star wheel h which drives pinions k, m, and an indicating pointer r. By means of a finger piece q the spindle of the pinion m may be raised against the action of a spring s to draw the pinion m out of gear with the pinion k so that the pointer r may be set to zero after a stroke. In a modified device the collar c is mounted on ball bearings. The ball-tether may consist of a closely-coiled spring 5, Fig. 5, attached to the ball and to the device by screwthreaded members 6. Over-running of the starwheel h may be prevented by a spring pressing on one face of the pinion k, or by a spring bearing on the teeth of the star wheel.

Abstract: 983,197. Pneumatic despatch systems. STANDARD TELEPHONES & CABLES Ltd. May 17, 1963 [May 18, 1962], No. 19681/63. Heading B8A. In a central transfer system for the carriers of a pneumatic despatch system a distributer 28, Fig. 1, for receiving carriers from multiple spacers 16 and delivering them to selected conveyer lines is curved substantially through right-angles for coupling to horizontally disposed conveyer lines 34. The arrangement permits reduction in height of the transfer system as compared with a system in which the conveyer lines are vertically disposed. In the example the carriers are delivered from horizontally disposed multiple conveyer lines 1 through multiple dischargers 5 to parallel belt conveyers 6. These transfer the carriers to multiple spacers 16 which are pivotable on axes 17 and selectively tipped by motor-driven sprocket belts 22 for discharging the carriers over curved shoots 24 into the hopper mouths 29, Fig. 4, of the distributers. Selectively operable deflector arms 37, 38, 39 are arranged in a wider portion 31 of the distributer below a bottle-neck 30 and are correspondingly curved in two planes for smooth transfer of the carriers to the selected horizontally disposed conveyer lines 34. Apertures 45 in the sides of the distributer permit the arms to be withdrawn clear of a central discharge path. The parallel belt conveyers 6 may be vertically adjustable about a pivot 15 to permit the connection to conveyer lines 2<SP>1</SP> at a lower level.

Title: Improvements in or relating to method and apparatus for wiping conduit sections
Inventor: BERNHARDT OTTO
IPC: C23C2/18
Filed: 1956-06-29
Abstract: <PICT:0810107/III/1> Excess coating material (enamel paint, hot pitch, tar or asphalt) is removed from the interior of a conduit by clamping the conduit between an end support and a nozzle and blowing gas through it. The exterior of the conduit, which may be of metal, plastic or other non-metallic material, may also be treated by passing it through an annular nozzle assembly.  As disclosed for treating magnetic material, rolls 12 receive the dip-coated conduit 15 on their underside and retain it magnetically.  The conduit is then passed through the ring nozzle assembly 13 and steam jets blow off the excess coating material.  The rolls are de-magnetized when the trailing end of the conduit 15 contacts the time switch 21.  The carriage receives the conduit, which strikes a switch 33 causing the carriage to be lowered by air cylinders 29, 28.  The air cylinder 36 causes the interior wiping nozzle assembly 26 to engage the end of the conduit which is now supported solely by its ends, the right-hand end engaging suitable stops (only one, 42, shown).  A blast of gas blows out excess coating material.  The nozzle assembly is retracted to release the conduit, which again lies on the carriage 27.  The latter now moves to a horizontal position and conduit 15 is removed by a conveyer 47. Non-magnetic conduits are carried on the tops of rolls 12 and the interior nozzle assembly is suitably modified.
